Product Description:

The IL12030A1TRP1 is an ironless direct-drive linear motor coil manufactured by Kollmorgen for the IL Ironless DDL Motors series. By moving freely over a magnet track without iron in the winding carrier, the coil avoids cogging and supports high-precision positioning in electronics assembly, metrology, and semiconductor transport equipment. Its ironless design also supports smooth low-speed travel and responsive motion during fine positioning moves.

The unit delivers a continuous thrust of 62 N at 25 °C while drawing only 1.8 Arms, giving it a force constant of 33.7 N/Arms for predictable current-to-force conversion. When brief acceleration is required, the coil tolerates a peak force of 240 N from a maximum drive current of 7.1 Arms. A rated output of 621 W supports demanding duty cycles, and the phase inductance of 2.6 mH helps moderate current ripple when the coil is driven by a PWM amplifier. The phase resistance of 12.2 Ω influences steady-state current draw at a given bus voltage, while the back-EMF constant of 27.5 Vpk/(m/s) helps describe speed-related voltage generation. Physically, the coil is 206.8 mm long, 25 mm wide, and weighs 0.42 kg, which keeps added moving mass low. Overall stack height above the way is 78.5 mm, helping the motor fit into low-profile linear stages.

Dynamic performance is supported by a motor constant of 7.8 N/√W, which indicates the relationship between continuous thrust and power loss. Thermal behavior is also described by a thermal resistance of 0.804 °C/W, which helps estimate winding temperature rise as heat is dissipated through the mounting surface. These characteristics make the coil well suited for motion systems that need smooth travel, fast response, and stable thermal operation over repeated cycles.
